This is unique source of information on the chemicals manufactured and imported in Europe. It covers their hazardous properties, classification and labelling, and information on how to use them safely.

Publishing information from dossiers

ECHA is publishing information included in the registrations dossiers on its website. This will then be freely available for all European citizens so they can be informed of any potential risks of the chemicals that they are using.

The information published covers the identity of the substance, the results of studies on its intrinsic properties and hazard profiles, the levels where no adverse effects are expected for human health or the environment, its classification and labelling, as well as guidance on its safe use.

If not claimed confidential, ECHA will also publish on the substance degree of purity essential for classification and labelling, total tonnage band, (robust) study summaries, information in the safety data sheet and the trade name.

Under certain circumstances, the IUPAC name can be claimed confidential. In these cases, the registrant must provide a public name that the ECHA can use for dissemination purposes.

Before submitting their dossiers, registrants have the opportunity to request that certain data be kept confidential and to check what information will be publicly available. Requesting confidentiality applies only to a limited set of data and requires a justification, which will be evaluated by ECHA. In case the confidentiality request(s) is rejected by ECHA, the registrant within a specified period can ask the Agency to review the rejection decision.

Practical advice on what could be published on the ECHA website from the registration dossier, how to claim certain data confidential and how to derive a public name can be found in the manual on “Dissemination and confidentiality under the REACH Regulation”. Before submitting a dossier registrants also have the opportunity to run the IUCLID dissemination preview to see what data might be published on ECHA’s website.
